Sega-Naomi

i have a naomi 1 board and it the image comes on for some minutes and then it just resets, i already changed the bios to the new-er rev. ones that i got, well i dont know where to look, can some one please help on this.

What are you using to power your Naomi? What type of I/O? Are you using GD-ROM system?

is your psu strong enough?

mine used to reboot when 3.3 and 5.0 were too low
